* When adding the carry bit to another value on X86, exploit the fact that the ↵Owen Anderson2010-09-212-0/+37
| | | | | | | | | | | | carry-materialization (sbbl x, x) sets the registers to 0 or ~0. Combined with two's complement arithmetic, we can fold the intermediate AND and the ADD into a single SUB. This fixes <rdar://problem/8449754>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114460 91177308-0d34-0410-b5e6-96231b3b80d8

* Add LiveInterval::find and use it for most LiveRange searching operationsJakob Stoklund Olesen2010-09-212-75/+41
| | | | | | | | | | | | instead of calling lower_bound or upper_bound directly. This cleans up the search logic a bit because {lower,upper}_bound compare LR->start by default, and it is usually simpler to search LR->end. Funnelling all searches through one function also makes it possible to replace the search algorithm with something faster than binary search. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114448 91177308-0d34-0410-b5e6-96231b3b80d8
